This patent describes a liquid-cooled piston for reciprocal movement within a cylinder of an internal combustion engine. It comprises: a generally cylindrical piston body having an outer peripheral surface with an annular groove defined in the outer peripheral surface; a ring carrier assembly disposed in the annular groove and having at least one peripheral groove adapted to receive a sealing ring, the ring carrier assembly includes an annular metallic body having an axially extending inner peripheral wall and a pair of upper and lower annular walls extend radially inwardly from the peripheral wall to form an inwardly facing, generally C shaped cross-sectional shape and enclosure means collectively defining a substantially closed, generally annular, integral coolant channel; and means for providing communication with the coolant channel so that in use a coolant stream can be directed to the coolant channel.
